Scout should be able to show you many places where you can improve your code.

Any framework usually comes with some performance costs/overheads but make make 
development more manageable and most mobile applications probably wouldn't 
benefit a heavyweight framework like PureMVC (IMO).

That can be an option and is likely to be faster and may not have all the 
components you needs.

There have also been many speed and performance improvements in recent versions 
of Apache Flex you might want to try out 4.12 and see if that improves things. 

Thanks,
